IGNITION SYSTEM (FOR H27 ENGINE) 6F2-9
INSPECTION
Inspect them for electrode wear, carbon deposits and Insulator
damage.
If any abnormality is found, replace them with specified new plug.
Spark plug air gap “a” :
1.0 – 1.1 mm (0.039 – 0.043 in.)
Spark plug type :
DENSO K20PR-U11/SK16PR11
NGK BKR6E-11/*IFR5J11
INSTALLATION
1) Install spark plug (3) and tighten them to specified torque.
Tightening torque
Spark plug (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
2) Install ignition coil assembly (2) securely.
3) Tighten ignition coil bolt (1), and then connect ignition coil
coupler.
4) Install ignition coil cover.
CAUTION:
When servicing the iridium/platinum spark plugs (slender
center electrode type plugs), do not touch the center
electrode to avoid damage to it. The electrode is not
strong enough against mechanical force as it is slender
and its material is not mechanically tough.
NOTE:
Under –25°C (–13°F), it is highly recommended to use the
spark plugs with an asterisk (*) for better engine starting
performance.
